    摘要： A multiphase superconducting cable connection structure includes a connection box (1) accommodating three conductor connects connecting a superconductor (201) of a cable core (102) of each phase extracted from a pair of 3-phase superconducting cables (100), a solid insulation member (2) fixed to an outer circumference of each conductor connect, and a metal flange fixing the solid insulation member (2) to the connection box (1). By fixing the metal flange (3) to the connection box (1) (a refrigerant vessel (11)), the conductor connect can be positioned and the conductor connector's movement caused as the cable core (102) thermally contracts can be reduced. The structure can help to position the conductor connect in the connection box and reliably hold it at a prescribed position.

    摘要： A first flange (11) and a second flange (12a) are superposed and fastened with a bolt (B) and a nut (N) in a fastening operation, to implement a fastening structure used at temperature lower than atmospheric temperature for the fastening operation. Assuming that the first flange (11) has a thickness L1 and a coefficient of linear expansion α1, the second flange (12a) has a thickness L2 and a coefficient of linear expansion α2, superposed first flange (11) and second flange (12a) have a thickness L, and the bolt (B) has a coefficient of linear expansion α, a relation of L·α ≥ L1·α1 + L2·α2 is satisfied, i.e. heat shrinkage of the bolt (B) is not smaller than the total heat shrinkage of the first and second flanges (11, 12a). Thus, impairment of sealing property due to heat shrinkage is avoided at a flange junction used at low temperature.

    摘要： A phase split structure of a superconducting cable includes three cable cores (102) each having a shield layer (203) provided around a superconductor, a splitter box (1) housing the three cable cores (102) extending from an assembly portion where the three cable cores (102) are assembled into the cable, in a state in which the cable cores (102) are spaced apart from each other, and a shield connecting portion (2) connecting respective shield layers of the cable cores (102) to each other within the splitter box (1). The shield connecting portion allows the cable cores to have their respective shield layers connected together with low resistance and each shield layer can pass a current substantially equal in magnitude to that which each superconductor passes. Thus in each shield layer a magnetic field can be formed having a level that can cancel a magnetic field generated from each superconductor. The structure can thus effectively prevent a large magnetic field external to the cable core.
